Scientists from Stellenbosch University came up with this unique formula.

Formula to make hand sanitiser from stale bread. The entire process took about a week and they managed to produce about 18 litres of alcohol-based sanitizers. The scientists said that in SA, kilograms of bread get thrown out each day because they are past their sell-by date. They wanted to put the waste to good use. The researches said that they will be publishing their formula and recipe to allow people all over the world to produce hand sanitizer from bread. Apparently, the end product smells a little bit like toast!
